6th GradeNegative numbersabout 2 minCCSS 6.NS.C.5CCSS 6.NS.C.7.c

Drop the tallest mountain into the deepest sea.

Lesson Plan

Explore positive and negative numbers with sea level as zero, then compare heights using absolute value.

  1. Question: Ask what students spot and what they are curious about. Read “Where would Everest's peak end up?” aloud. Have each student guess and say why.

  2. Big idea: Pause. Ask a student to say the idea in their own words.

  3. Question: Read “Mauna Kea, base to top, vs. Everest?” aloud. Have partners explain their guesses to each other.

  4. Real-world application: Ask: Where else have you seen this?

  5. Your turn: Have students try their own. Ask them to predict before they test.
